The large vermilion torii gate standing in the lake serves as a landmark for the entrance to Lake Hamana from the Pacific Ocean.
The water depth around the torii gate is shallow enough that it can be reached on foot during extremely low tide.
The area is a well-known location for 'shiohigari' (clam digging), a popular recreational activity in the spring.
Lake Hamana is technically a lagoon, having been connected to the ocean following a massive tsunami in the late 15th century.
The beach is located near the site of the former Bentenjima hot spring resort area.
Bentenjima Beach is defined by its iconic red torii gate, which stands directly in the waters of Lake Hamana rather than on a traditional shrine shoreline. The area is situated on a sandbar accessible via the Bentenjima district, offering a unique intersection of lake views and ocean-influenced coastal scenery. Visitors can walk along the shoreline or participate in clam digging, which is a local seasonal tradition. The beach area is connected to the mainland by the Bentenjima Bridge, which provides a vantage point over the shallow waters of the inlet. The park surrounding the beach features pedestrian paths and designated areas for viewing the lake's sunset and the illuminated torii gate.

Check the tide charts before visiting, as the ability to walk out toward the torii gate depends entirely on the tide level.
Bring water shoes if you intend to walk on the sandy lake bottom, as shells and debris can be sharp.
Visit during the late afternoon to catch the sunset, which aligns beautifully behind the torii gate.
Assuming the water is suitable for deep-sea swimming; the area is better suited for wading and shallow-water recreation.
Clam digging activities are restricted to specific months in the spring and early summer; check local regulations annually.
Respect local clam harvesting regulations and size limits during the seasonal digging periods; do not climb on the torii gate.
